The convergence properties of mixed-norm algorithms
as it applies to echo cancelers under general error criteria
is derived for correlated and identically distributed inputs.
The convergence analysis of this class of algorithms is car-
ried out using the linearization process of the error non-
linearities. Necessary and suficient conditions for conver-
gence are derived for the independent input case.
where f( e ( k ) )and g(e(k)) are the error nonlinearities,
W N ~and W F ~are the true impulse responses of the near-
end and far-end sections, respectively, and where P N and
